Answer: 0.313 rad/s
Explanation:
The equation that relates the velocity 
and the angular velocity 
in the uniform circular motion is:
(1)
Where 
is the radius of the space station (with a diaeter of 200m) that describes the uniform circular motion.
Isolating from (1):
(2)
On the other hand, we are told the “artificial gravity” produced by the cetripetal acceleration 
is 
, and is given by the following equation:
(3)
Isolating :
(4)
(5)
Substitutinng (5) in (2):
(6)
This is the angular velocity that would produce an “artificial gravity” of 9 .
Answer:
Producers are organisms that create food from inorganic matter. The best examples of producers are plants, lichens and algae, which convert water, sunlight and carbon dioxide into carbohydrates. Consumers are organisms that cannot create their food.
Answer: (2) Use the Momentum Principle.
Explanation:
In fact, it is called the <u>Conservation of linear momentum principle,</u> which establishes the initial momentum 
of the asteroids before the collision must be equal to the final momentum 
after the collision, no matter if the collision was elastic or inelastic (in which the kinetic energy is not conserved).
In this sense, the linear momentum 
of a body is defined as:
Where 
is the mass and the velocity.
Therefore, the useful approach in this situation is<u> option (2)</u>.
Answer:
Isovolumic
Explanation:
In thermodynamics, the process whereby A real gas is changed slowly from state 1 to state 2 and in this process there's no work done on or by the gas is called Isovolumic process.
Answer:
3 m/sec(squared)
Explanation:
a=change in velocity/time
a=v-u/t
a=36-0=36/12
a=3m/s(squared)
